yBeit known that I, ABDENAGO Roser, a citizen of the United States, residing at Chicago, in the county of Cook and State sof Illinois, have invented certain and useful Improvements in Lid-Operating Mecha-y nism, of which the following is a description. j .j

My invention'relates to. an improvement in lid-operating mechanism, and more particularly to a stay arm operating means for use on phonograph cabinets, trunks or the like, for raising, lowering and holding in place the topsl ids or coversof ythe same@ One ofthe objects of `my invention is to provide lid-operating mechanism as above described, which will tend to mechanically tion, considering weight, andthe speed ofy -the..raisiiig orlowering operation may be regulated. f

IVIany otherobjects and advantagesof the j 'construction herein shown and described will be obvious to those skilled in the art.`

To this end` my invention consists in the novel construction, i arrangement and conibination of parts hereinshown and de` particularly pointed out' scribed, and more in the claims.

In the drawings, wherein like reference indicate like or corresponding' characters parts,y i f Fig. 1 is a sectional view of device taken on the line 1-1 of Fig. 2;

Fig. 2 is an elevationfthereof, the dotted lines showing a change in position; and

Fig. 3 is a sectional View of the same, taken on line 3-3 of Fig. 2.

In the drawings, wherein I 4have illus` trated the preferred embodiment of my invention, 1 indicates the cabinet, trunk, case or the like, which in the present instance we will assume as being the cabinet of a talking machine, while 2 represents the lid or cover for the same, the latter being hinged or otherwise secured at one edge, not shown, to the cabinet. n

A bracket or plate, L-shaped in cross section, is arranged with one of its legs 3 ,tactof the stop 9 with the shoulder 1l. link 6-7 is formed with any offset portion 413` intermediate` its endsy for `the securemeiit ofone endof a tension spring llldfor a pur`y secured to the ton cdgeof `the cabinet means `of suitable screws 4er' their equiva-y lent fastening means, and theother leg i vertical wall of the cabinet. j n bent lever or link, having arms 7, ispivotedat one end adjacent .the lower arranged to'lie against the inner face of the edge of the plate 5 by means of apin` 8` or the like, 'said` pivoted end of` ,the link Gand" having .a lug 9, formed thereon to abut j againstv shoulders 10 and 11 provided on the lower edge of the part 5. as isclearly `shown w in Fig. `2, and thus provide limits or stops for the pivotal movement of the link.` Another stopinember 12 is arrangedr on` the part 5 to engage the link prior to `the `con-` 4 pose to be hereinafterV described.

v A `stay armorplink 15 isv pivotally con-Y nected at one'end 16 to the lidor cover 2l by any suitable or preferred means, and thek The i adjacent ends of both the links are pivotallv interconnected by means of apin `17 or the `v like,1so that when the lid is raised or ,lowered, both yof the links willy be moved in j unison therewith., An `elongated slot 18,

having an offset enlargement 19, is formed `in the portion l3 of the brac-inetA toprovide a guide-way during the movement `of the stay arm or link15 between the fullelire. and dotted-line positionsshown.

An offset portion 20 is provided adjacent the lower edge ofthe plate 5. and between said offset portion 20 and the leg 3 there is mounted a screw 21, as shown.` A. nut 22 is `threaded on said screw 'for a purpose to be hereinafter described.

A bar 23, havinggan yelongated slot 2.4 extending longitudinally.thereof, is mounty ed upon a pivot pin 25 carried by the bracket, said slot having a 4series of indenta-` tionsv 26 arranged therealong for `purposes of adjustment. One end 28 of the bar` 23 is arranged to be engaged by the nut `22,

and the other end 29 is adapted to have the end of the spring 14 secured `thereto sothat when the spring is in place, as

shown, and connectedbetweenthe parts I3 i and 29, the end 29 of the bar will be pressed upwardly into contact with the nutv 22, thus .securely holding the bar stationary and exerting an upward stress on the stay arm.

The tension of the spring may be manually adjusted whenever desired, inV orderl to adjust the device for the weight of thel cover, or to accelerate or retard the speed of per edge of'the"bar,so that a suitable tool may be inserted through the enlargement 19 of the slot 18 to engage the lugs 30 to move tliebar laterally of the'pivot pin.

From the foregoing description it will be obvious that when the lidiis in the closed po` sition, with the mechanism arranged as shown by dotted lines in Fig. 2, then as soon as an initial lifting movement is given to the lid, the tension'ot thespring 14 will tend to yieldablyk assist or accelerate the lifting oit the lid 'so as to raise it auton'iatically until it comes to its fully open position, as shown in full lines in said figure. In order to close the lid, the initial 'lowering movement is given Vtothe lid, whereupon the spring ietf increasingly retards the 4normal lowering movement ofl the lid, acting against the weight ot the lid,'so as to slowly lower the lid to the positionshown in dotted lines.

Having thusdescribed my invention,- it4 is `obviousthat various immaterial modifications maybe made in thev same without deiliarting from the spirit ot my invention; .hence `I do not wish to be understood as limiting myself to the exact Jform', construction,

varrangement and' combinaticn ot'parts herein shown and described, or uses mentioned. That I .claim as new and desire to secure by Letters Patent is:y

l. Lid-operating mechanism comprising a A link having one end pivotally 'connected to a lid, a link operatively pivotally connected at one end to a. container, the other ends of said links pivotally interconnected, a tension spring secured at one end to a stationary part and at its other end to said second-- mentionedlink to yieldably retard the closing of the lid and accelerate the raising thereof, and means operable from the eXte-k rior oip the'container to adjust the tension of said spring.

2. Lid-operating mechanism comprising a bracket adapted'y to be mounted on a container, a link pivotally connected at one end to a lid, 4a second link pivotally connected vto said bracket, the other ends of said links pivotally interconnected, a bar pivoted intermediate its ends on said bracket, meansA for adjusting` said bar longitudinally of its pivotal axis, and a tension spring connected at one end to said 'bar andy at itsj other end' to said last' mentioned lin'kl to yieldably retard the closing'of the lid and acceleratethe`- raising thereof.

3, Lid-operating mechanism comprisinga y bracket adapted to be mounted on a container, a linky pivctally connected at one end to a lid, a second lin-k pi-votallj;7 connected to said bracket, the other ends ot said links pivotally interconnected, a bar carried by said bracket and movablebodi-ly l'ongitudi?v nally of itself, a tension spring connected at one vend to said bar and .at its otherend to said last mentionedV link to yieldablfy retard the closing of the lid and accelerate the' raising thereof, and means fer adjustablymoving said bar to vary the tension of saidspring.

4:. Lid-operating mechanism comprising a bracket adapted to be mounted ona con-y tainer,'a link pivotally connected at oneend to a l'id, a second link pivotally connected at one endet said bracket, the other `ends ofv said links pivotally interconnected, bar" pivoted intermediate its ends ment, means for adjustablymoving saisdbar laterally ot its pivotaly aXis, anda tension spring connected at one end to said last.; mentioned link and at its other end to'said bar, whereby the opening of saidvlid .is yieldably accelerated and the closing there: of is yieldably retarded.

In testimony whereof, I have hereunto signed my name inthe presence of twol subscribing witnesses;
